  "abstract": "We analyze the time series of Ca ii H-line obtained from Hinode/SOT on the solar limb. The time-distance analysis shows that the axis of spicule undergoes quasi-periodic transverse displacement. We determined the period of transverse displacement as ~40-150 s and the mean amplitude as ~ 0.1-0.5 arcsec. For the oscillation wavelength of $\\lambda$ ~ 1/0.06 arcsec ~ 11500 km, the estimated kink speed is ~ 13-83 km/s. We obtained the magnetic field strength in spicules as B_0 = 2 - 12.5 G and the energy flux as 7 - 227 J/m^-2s.",
